From planned suburbs to private wells in Douglas County
Douglas County had 357,978 residents at the 2020 Census, with a small slice of Aurora, about 2,500 people, inside its borders. Most of the population lives in planned suburbs such as Highlands Ranch, Lone Tree, Parker and Castle Rock. Those homes were mostly built in recent decades, with copper or PEX supply, plastic drains, finished basements and, in many cases, sump pits and sprinkler systems.
As those suburbs age, the original parts wear out on a schedule: water heaters, pressure reducing valves, toilet fill valves, sump pumps and backflow assemblies. Homes built roughly 1978 to 1995 in older sections may contain polybutylene supply pipe. Gas heaters need a proper high-altitude setup, and replacement generally requires a permit and inspection, which we handle.
The southern and eastern parts of the county are rural. Around Franktown, where our headquarters sits, and on acreage near Parker and Castle Rock, private wells and septic systems are common. A failed pump, switch or pressure tank cuts water to the house entirely. We service those systems, and septic tank pumping stays with septic service companies.

Suburban and rural tips for Douglas County

- Test sump pumps in springPour water into the pit and confirm the pump starts and stops. A battery backup protects finished basements when storms knock out power.
- Check well pressure tanksRapid clicking from the pump when a faucet runs often means a waterlogged pressure tank. Fixing it early saves the pump.
- Plan heater replacementsIf your heater is more than ten years old, plan its replacement before it fails. Leaks in finished basements cost far more than a planned swap.
